RIVET CATCHER.

Application filed June 19, 1920. Serial No. 390,221.

To aZliolzom it may concern:

Be it known that 1, JOHN M. Caravan a citizen of the United States.residing at- Covington, in the county of Kenton and State of Kentucky,have invented certain new and useful Improvements in Rivet Catchers, ofwhich the following is a specification.

This invention relates to improvements in arcasing for cutting tools, asfor instance a rivet clipper, whereby the. head which is clipped fromthe rivet is caught by the easing and thus prevented from striking anearby workman.

One object of the invention is to provide a casing for the end portionof a cutting tool with a housing formed in the end of the casing toreceive the clipped head of a rivet or the like.

Another object of my invention is to provide a rigid casing with abearing strap or member extending across the open under side of thecasing so that the cutting tool can move about a horizontal axis on saidbearing member and in this way make it possible for the'cutting end ofthe tool to pass beyond the casing.

Still another object 0t my invention is to form a rigid casing withflexible side portions and a flexible strap member connecting the edgesof the side portions so as to allow the. fiexibleportions to be grippedabout the tool and to allow also the required amount of: play forthe't'ool as it moves about a horizontal axis on the bearing member inpassing beyond the casing end.

A further object is to provide a casing with a metal rigid body portionand a covering of leather or other yieldabl'e material, which projectsbelow the edge of the metal at the bulged end so "as to prevent therivet head from slipping out between the casing and the tool.

Another object is to secure the yieldable covering to the metal bodyportion in such a manner as not to interfere with the catch ing of therivet head in the housing of the casing.

Other forms of structure embodying my invention will suggest themselvesto those skilled in the art, but the preferred form will be understoodfrom the following description and claims considered in connection withthe accompanying drawings.

Fig. 1 is a side elevation of my invention;

Fig. 6 is a view like Fig.1. 3 showing the relative arrangement ofcasing and cutting tool after the rivet head has been clipped.

The casing comprises a concave rigid strip 1 of metal or other suitablematerial, to the outside of which is secured covering members 2 and 3 offlexible material, such as leather; these parts being secured togetherin any suitable manner, as for example by means of rivets i and 5. Theforward end portion of the casing is formed with a dccided bulge asindicated at 9, so as toprovide a housing for the reception of thesevered head of a rivet or the like. as illustrated in Fig. 4. Themember 2 is separate from member 3 and is riveted along the back ofstrip 1 as at t so that the side portions 6 are free for flexure. Thepart 3 of the covering projects below theedge of the bulged portion 9,as indicated at 3 in Fig. With this arrangement the .material ii beingyieldable, affords added protection inasmuch as the rivet head catcheraccommodates itself to the "irregularities of the material. thuspreventing rivet heads and steel slivers from Flying, and furthermorepermits the rivet head catcher to be moved forward or backward withgreater facility. The rivets tor securing the covering i) to the metalmeniher 1. are placedaway from the tront end of the casing. as forinstance along the sides "as at 5, so as to avoid any danger of thesevered rivet head striking a head of one otthese rivets 5 and glancingout between the casing and the cutting tool as above referred to. Thusthe covering 3 is extended back over the bulged end of the member 1. Thecovering 3 is split and overlapped as at 3 and 3 so as to conform to theshape of the housing. p

A curved strap or bearing member 7 has its endsattached to the sideportions 6 in any suitable mannery as for instance by means of rivets 8.This member 7 is located at a point substantially midway of the lengthof the casing and is adapted to form a bearing means for the cuttingtool as it moves about a horizontal axis in order for its cutting end topass the" end of the casing after the clippii'ig' of the rivet head.

The casing is made sufficiently large to allow the required freedom ofmoveme-ntof the cutting tool during the clipping operation; the fie.'ble bearing member '4' allowing suiiicient give as the tool is causedto pass beyond the housing end of the casing. The flexible portions 6and 7 serve also as a means for holding the casing in proper positionupon the cutting tool.

This device is especially adapted for use in connection with a pneumaticgun or other power tool for clipping rivet heads, and as the toolengages the rivet head it bears an angular relation with the length ofthe casing, as indicated in Fig. 8. Then as the tool clips the rivethead, this angular relation is increased to the extent that the end ofthe tool passes beyond the end of the cas-- ing as indicated in Fig. 4.The head 11 is caught in the housing 9 and is thus prevented fromcausing injury.

By providing the angular play between the tool and the casing, it ispossible to make the casing rigid and at the same time allow the end ofthe tool to pass beyond the casing.

This results in a more durable structure. Then with the reinforcementfor the housing, it is prevented from being torn by the force of therivet head as it flies from the rivet. And furthermore the severed rivethead is prevented from slipping past the edge of the housing, as aboveexplained.

' Other advantages will be apparent to those who are familiar with theart to which this invention relates. i

lVhat I claim is:

1. A rivet head catcher, comprising a casing member adapted to beapplied to a clipping tool or the like, said casing being open and freeof obstruction along its one side, a single bearing means providedbetween the side walls of said casing, and extending across said openside in such a manner that the cutting tool is free to move about saidbearing means on "a transverse axis during the clippingoperation so asto allow the cutting end of the tool to pass beyond the end of saidcasing as part of the same operation.

2. A rivet head catcher, comprising a rigid bracing member, a coveringof flexible material upon said rigid member, said rigid member and thecovering therefor together forming a casing for a clipping tool or thelike, the side walls of saidcovering throughout part of the length ofthe casing extending beyond said rigid member and being free forbending, a yieldable bearing member extending between the side walls ofsaid yieldable extensions and adapted for move- .ment toward and awayfrom said casing.

3. A rivet head catcher, comprising, a concave back part of rigidmaterial, side walls of yieldable material extending from the marginalportions of said back part throughout-the rear portion thereof, themarginal of a rivet or the link portions of said yieldable side wallsbeing adapted to be snugly embraced about a cutting tool for grippingthe same during its operation in said casing.

7. A rivet head catcher, comprising a casing member adapted'to beapplied to a clipping tool or the like, said casing being so constructedas to allow relative movement of said tool for clipping the head of arivet or the like, said casing including a metal body portion to receivethe severed part, said body portion being provided with an extension ofyieldable material from the front edge thereof corresponding to, thecutting end of the tool and adapted for engagement by the same.
